Etymology: "Perennitas" is a Latin noun meaning "perpetuity" or "long duration," built from "perennis," "lasting through the years." That adjective is itself a compound of "per," "through" or "throughout," and "annus," "year," so the word literally describes something that lasts through the years. The same root gives English "perennial," which in botany still means a plant that survives year after year, and this is the older, more concrete sense that the Latin noun grew out of. In Latin, "perennitas" was used of things that endure: a family line, a city, a reputation, or a state's permanence. Its later life owes much to Christian writers, who applied it to God and to eternal life, where it described a condition beyond time rather than merely a long run of years. English took the word in the sense of perpetuity, and it is now rare outside Latin study and theology, though its English relative "perennial" remains common.
